III/III! /IIIIIII Y, v 70 3g! m WILLIAM MGINTOSH, OF PLAINFIELD, NEWJERSEY.

AUTOMATIC TRUCK-CELLAR FOR LOCOMOTIVES.

To all whom it may concern:

Be it known that I, WILLIAM MoINTosH,

a citizen of the United States, residing at Plainfield, in the county ofUnion and State of New Jersey, have invented certain new and usefulImprovements in Automatic Truck-Cellars for Locomotives; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others sln'lled in the art to which itappertains to make and use the same.

My present invention is particularly directed to the improvement ofautomatic lubricators of the so-called truck cellar type, for use onlocomotives and other railway vehicles and, to this end, the inventionconsists of the novel devices and combinations of devices hereinafterdescribed and defined in the claims.

In automatic truck cellars, the oil cellar is yieldinglypressed upwardagainst the body of the axle journal, so as to compensate for wear andto keep the oil-saturated waste or packing in contact with the journal.

My invention provides an extremely simple and highly efficient devicefor the above purpose, which, in itself, may be Very easily manipulated,thereby permitting easy application of the oil cellar to the journal andeasy removal thereof from the journal, whenever desired.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view partly in side elevationand partly in vertical section, showing the journal box of the type usedin locomotives and illustrating my invention applied thereto; Fig. 2 isa vertical section taken on the line m m of Fig. 1; Fig. 3 is afragmentary view, in horizontal section, taken on the line m of Fig. 2,looking downward; and Fig. 4 is a fragmentary view corresponding in theline of its section to Fig. 2, but showing the operation of one of thecellar retaining plungers contracted.

Serial No. 540,594. I

The numeral 1 indicates an approximately inverted U-shaped journal boxof the type used in locomotives, and which journal box is adapted to fitbetween depending arms of heavy side frames not shown. Seated within thebox 1 is the customary bearing brass 2 which rests on top of the journalof the axle 3, which axle is shown only in Fig. 2. The oil cellar 4,which may be of usual or any suitable construction adapted to fitbetween the depending flanges of the box 1, is adapted to closely'engage the under side of the journal of the axle and to hold a suitableoil saturated packing, such as waste,

bars, and at their central port-ions they are provided with dependingsockets 9 having inturned ledges at their lower extremities adapted tosupport coiled springs 10. From the sockets 9, reinforcing ribs 11extend outward on the yoke bars 8 and terminate close to the loopedportions 5 of the anchor bars 5 and thereby hold the latter with theirbent ends seated in the bolt holes 6, as long as the said yoke bars arein working position.

WVorking through each yoke socket 9 and through the cooperatingcoiledsprings- 10 are cellar supporting plungers or bolts 12 provided attheir upper ends with flanged heads that rest upon the said springs andare normally held by the said springs seated within depressions orpockets 13 formed in the bottom of the end portions of the oil cellar 4.The plungers 12 depend through the yoke sockets 9 and are provided attheir lower extremities with transverse fulcrum pins or portions 14, andabove said fulcrums they are formed with long transverse slots in whichplunger lock levers 15 are located. These lock levers 15 are providedwith depending hand pieces 16 and they are formed with notches or seatsthat rest directly upon the said fulcrum pins 14L The upper portions ofthe lock levers 15 are adapted norm ally to work freely within thesurrounding coiled springs 10 and they are provided in their extremeupper ends with notches 1'? that are adapted to engage the lower edgesof the yoke sockets 9, when the plungers are drawn downward as shown inFig. 4 and the said lock levers are rocked on the fulcrum pins 14, asalso shown in said Fig. t. These manipulations may be easily produced bytaking hold of the hand piece 16.

There is suflicient spring in the so-called anchor rods 5 to permit thelaterally bent ends thereof to be engaged with the bolt hole 6regardless of the slight irregularities or variations in the spacing ofthe said holes. When the yokes 8 are to be applied in working positionor to be removed therefrom, the plungers 12 should be drawn downward,the springs 10 compressed and the said parts locked in such relativepositions in respect to the yokes as shown in Fig. 4:, by themanipulation just above described. hen this is done, the oil cellar 4,if in working position, will drop with the plungers and away from theaxle journal, but it may then be easily lifted off from the plungers andremoved endwise from the journal box. On the other hand, when the yokebars are applied to the anchor rods with their plungers depressed, theoil cellars may be readily inserted into the journal box and seated uponthe plungers and then, when the lock levers are rocked on the fulcrums14;, so that their upper portions are alined with the respectiveplungers, the springs 10 will be released and will force the plungersupward until they have carried the oil cellar against the axle journal.

The above noted manipulations, as is evident, may be very quickly andeasily accom plished, so that the application or removal of the oilcellar is made a very simple matter. At the same time, when the springpressed plungers are released and allowed to become operative, they veryefliciently hold the oil cellar in working position and cause the sameto maintain engagement with the ournal and to take up all slack incidentto wear. In fact, when the spring pressed plungers are operative, theyhold all of the parts positively locked together, in which conditionthey will remain indefinitely until the said spring pressed plungers areintentionally drawn downward in the manner already described.

The factthat the improved device may be readily applied to journal boxesof standard construction, without remodeling thereof, and without theuse of bolts, nuts, cotters or similar devices which are liable to bearred or rattled loose, is highly important.

The so-called automatic truck cellar above described, while especiallydesigned for locomotives, is, nevertheless, capable of gen eral usewherever a lubricating device of this character may be found desirable.

hat I claim is:

1. The combination with a journal box and an oil cellar, of a yoke barrelatively fixed in respect to said journal box and spanning the spacebelow said oil cellar, a spring pressed plunger working through theintermediate portion of said yoke bar and pressing said oil cellarupward, and means for locking said plunger to said yoke bar, in aretracted position.

2. The combination with a journal box and an oil cellar working therein,of anchor brackets applied to the lower portions of said journal box, arigidly held yoke-bar detachably seated on said anchor brackets andspanning the space below said cellar, and a spring pressed plungerworking through said yoke-bar and engageable with the lower portion ofsaid oil cellar.

3. The combination with a journal box and an oil cellar working therein,of anchor rods with looped and laterally bent ends, which latter aredetachably seated in holes formed in the lower portions of said journalbox, yoke bars having central sockets and depending ends, which latterare detachably seated in the loops of said anchor rods, spring-pressedplungers working through the sockets of said yoke bars and havinginterlocking engagement with the bottom of said oil cellar, and locklevers fulcrumed on said plungers and engageable with the sockets ofsaid yoke bars to hold said plungers in retracted positions,substantially as described.

4. The combination with a journal box and an oil cellar working therein,of a yoke bar supported below said cellar and provided with anintermediate socket, of coiled springs seated in the socket of said yokebar, a plunger working through said socket, yieldingly supported by saidspring and engageable at its upper end with a pocket in the bottom ofsaid oil cellar, the said plunger at its lower portion being providedwith a fulcrum and above said fulcrum with a transverse slot, and a locklever mounted on said fulcrum, provided with a depending hand piece andhaving an upper end portion adapted normally to work within said coiledspring but engageable with the lower portion of said yoke socket to holdsaid plunger in a retracted position against the tension of said spring,substantially as described.
